Windows 10: Reset Router No Longer Sure If I Am Secure

I must have at some point changed my router/ modem login info from the default admin/password combo to something else but I could not remember it and I could not log into my router by going to 192.168.0.1 so for the first time I pressed the reset button and set it to factory defaults. That was nerve wracking : ) Subsequently I was able to go to 192.168.0.1 and enter the default user name admin and the default password (password) to something else and logged out and logged back in again to make sure it worked and it did.

I should have looked at Network settings before doing all this since I am not entirely convinced that I am safe or that I am not open for business shall we say to someone looking to use my internet connection.

I guess I can post more pictures if these are not enough. I have intentionally turned wifi off. I guess what concerns me is that in one of the pics it shows Network status ethernet public network and for some reason that looks unfamiliar to me.Thanks.

How to factory reset Cisco 1700 Router

Hopefully I can help you here....its a very common thing to happen.


First, I take it you dont know the passwords for console access or telnet/ssh?

I will assume that these devices belong to you.

step 1. Plug a cisco console cable into a serial port on your pc
step 2. Plug other end into Cisco console port
step 3. Using hyperterm or putty or similar connect to the serial port
step 4. boot router, and make sure you clearly can see the output (this confirms you have good serial comms)
step 5. if this fails, adjust the comm port settings (9600, 8,1,n are the default)
step 6. now you have to do the only hard part...send the break command:

Break command list: Break Commands

Go down the list and match your OS and SW and try the sequence suggested.

If this fails several times do what I do: Install putty (free) and then to send a break so you can get into rommom just hit "ctrl-a b".

 

Router behind a router = more secure?

Thanks.

So it is more secure from both exploits and brute force to have router > Router > Computers. An attacker would have to find exploits in both routers before gaining access to a network?

I'm not that worried, I just wanted to know the theory as I seem to get conflicting information. I had always assumed that having a router behind a router would be better security-wise.

I am pretty sure that my router would be on the list of those compromised in Vietnam by malware. The malware only changed the primary DNS for the router, so I would still not be immune to this kind of attack if someone gained access to my internet facing router, but it got me thinking more about security.

 

router logs DoS attack from a local PC....

Well you did not say that you don't really know what you are doing. It's not a problem of course, but it changes things a little.

It's not even clear if the PC or the router is the problem at this time, so I suggested that you disable some unnecessary things which are usually known to cause many problems, sorry if those were too complicated.

• You could reset some network related stuffz on the PC as a next step. Open an elevated command prompt (run as administrator), and enter the followings on the PC:
  netsh int ip reset reset.log
  netsh int ipv6 reset
  netsh winsock reset
  netsh branchcache reset
  netsh advfirewall reset
  (note: You can export your current firewall rules in the "group policy" before the reset if it's needed for some reason)
  
  
• Btw, Would it be a problem to reset the router to the default settings if the things we are trying will not help? There is a menu point for that called "factory settings" (and also a little hole on the back if you prefer that one).. the Administrator username in the router after the reset would be admin and the password is probably on a sticker at the bottom of the router (special settings needed to go online with your ISP might be also necessary)
  This is not needed now (not yet), but perhaps the source of the problem is at the router and not the PC in question, so we may come to that eventually.

ps.: Do you have a second network card you could test in that PC and a different cable to rule out some hardware issues on the PC side?
